## Unit description of WACE Maths Methods Unit 3 Year 12 ATAR Course

The study of calculus of WACE Maths Methods Unit 3 Year 12 ATAR Course continues with the derivatives of exponential and trigonometric functions and their applications, together with some differentiation techniques and applications to optimisation problems and graph sketching.

It concludes with integration, both as a process that reverses differentiation and as a way of calculating areas.

The fundamental theorem of calculus as a link between differentiation and integration is emphasised.

In statistics, discrete random variables are introduced, together with their uses in modelling random processes involving chance and variation.

This supports the development of a framework for statistical inference.

Access to technology to support the computational aspects of these topics is assumed.
